This study was designed to evaluate occupational health and
safety advice services, operating and giving advice in GP waiting
rooms, as closely as possible to how they existed at the time of
commencement of the study, without any major modification being
made to the type of advice they gave. Voluntary participants were
asked to complete standardised questionnaires gathering information
on the hazards to which they were exposed at work, their working
environments and possible work-related symptoms along with other
relevant demographic data. The provision of information, advice,
health surveillance and support to working participants identified
in need of help was performed according to established protocols
already in operation at the occupational health projects.
